This is the series of "How to" Document Workflow with SharePoint using Visual Studio 2008 (using the .NET Framework 3.0 for backward compatibility to Visual Studio 2005). I have created video's that show the most common requests that I have seen around MOSS/SharePoint 2007 workflow & document workflow.

The .NET Framework 4 makes it easier than ever to implement WCF services using WF. We'll demonstrate just how easy it is by modeling a long-running, durable and instrumented workflow based on a real-world business case without having to write any code.

This month's column describes how to use WCF for communication between a workflow and a host application in Windows Workflow Foundation 3. This knowledge should help developers with their efforts using WF3 and prepare them for WF4, where WCF is the only abstraction over queues (referred to as "bookmarks" in WF4) that ships with the framework.

Design patterns provide a common, repeatable approach to solving software development tasks, and many different patterns can describe how to accomplish a certain goal in code. When developers begin working with Windows Workflow Foundation (WF), they often ask about how to accomplish common tasks with the technology. This month's column discusses several design patterns used in WF.

With the NET Framework 3.5, Windows Workflow Foundation can now truly be integrated with Windows Communication Foundation. This column describes how the integration works and how to make use of it effectively.

State Machine workflows represent a different way of visualizing program logic. Rather than flowing from activity to activity like sequential workflows, State Machines transition from state to state. Learn about uses for State machines and see how to design and build a State Machine workflow with Windows Workflow Foundation.
